The yellow battery icon means Low Power Mode is on; it does not indicate battery damage. To remove it, switch Low Power Mode off in Settings. The menu path depends on your iPhone model.
Turn off the yellow battery icon in Settings
- iPhone 15 or later: Open Settings > Battery > Power Mode, then turn off Low Power Mode.
- iPhone 14 or earlier: Open Settings > Battery, then turn off Low Power Mode.
Menu labels can vary with iOS version or language. Apple documents these paths in its Low Power Mode instructions.
Other ways to switch it off
- Control Center: Use the Low Power Mode control if it is available there. Apple notes that adding the button may be part of Control Center setup.
- Siri: Ask Siri to turn off Low Power Mode.
- Charging: Apple says Low Power Mode turns off automatically when the iPhone is charged to 80% or higher. You do not need to wait for this threshold if you want to switch it off manually.
Apple documents Control Center and Siri as alternate controls in its Power Modes guide.

What changes when Low Power Mode is off?
Low Power Mode reduces background activity to extend battery life. While it is on, Apple says the iPhone may reduce display brightness and visual effects, set Auto-Lock to 30 seconds, temporarily pause iCloud Photos, turn off automatic downloads and email fetch, and turn off Background App Refresh. Some tasks may also run more slowly. Turning the mode off removes those Low Power Mode limits, but the battery may drain faster.

Why might it turn on again?
Adaptive Power is a separate feature from the yellow status icon. On supported iPhone 15 Pro or later models, Adaptive Power can make automatic adjustments and, when enabled, can turn on Low Power Mode below 20% battery. When Low Power Mode is active, the icon is yellow regardless of how it was enabled. Availability and defaults depend on the iPhone model and software. See Apple’s Power Modes guide for details.
